Who pays for portable batteries and accumulators in Denmark?

Producers and importers are required to pay for the quantity of portable batteries and accumulators which they have placed on the Danish market. The payment is collected by SKAT, the Danish Customs and Tax Administration. See the current payment rate for portable batteries and accumulators, which have been placed on the market.

Do you have a responsibility for reselling batteries in Denmark?

Environmental legislation on batteries and accumulators sets out producer responsibility; this means that if you produce or import batteries in view of reselling them in Denmark, you must contribute to the organisation and financing of take-back and management of those batteries when they reach the end of their service life.

Does Denmark have a standard for lithium-ion battery fire and explosion testing?

Denmark also lacks specific protocols for Lithium-ion battery fire and explosion testing, e.g., UL 9540A, which is a benchmark test recommended in many other countries. Danish guidelines may furthermore provide more clarification on when and which suppression systems should be installed, depending on BESS design parameters.

What are the safety requirements for stationary batteries?

Article 12 describes requirements for technical documentation that covers the safety requirements for stationary batteries under normal use. This includes tests for safety parameters as described in Annex V - Safety parameters and Annex VII - Parameters for determining the state of health and expected lifetime of batteries.

What are the test standards for a battery?

No specific test standards are mentioned. In SE1, the suggested test standards for thermal propagation and fire are IEC 62619 and UL9540A. NO1 recommends choosing batteries with good documentation of safety testing from a recognized supplier.

Are lithium-ion batteries a viable option for energy storage and balancing grids?

Aside from presenting a viable opportunity for energy storage or balancing electrical grids, BESS present significant fire and explosion risks, due to employment of Lithium-ion batteries (LIB), which are susceptible to thermal runaway (TR).
